In a bowl, sift together the flour, baking soda, and baking powder. In another bowl, beat together the sugar and butter with a mixer until smooth. Beat in egg and vanilla. Slowly blend in the flour mixture.
Using your hands, form small, round dough balls and place them on ungreased baking sheets.
Press down with your thumb into each ball to make an indentation. Place 1 teaspoon preserves into the center of each cookie.
